Efficacy and Prognostic Indicators of Isatuximab, Pomalidomide, and Dexamethasone (IsaPd) in Daratumumab-Refractory Multiple Myeloma Patients: A Multicenter Real-World Study.

ABSTRACT: This multicenter real-world analysis evaluated the efficacy of isatuximab, pomalidomide, and dexamethasone (IsaPd) in 51 patients with multiple myeloma (MM) who were refractory to daratumumab (Dara-R). The majority were under 70 years old (60.8%), predominantly female (56.9%), and heavily pretreated, with 74.5% being triple-class refractory (TCR); 32.1% of the 28 patients with cytogenetic data had high-risk abnormalities. The overall response rate (ORR) was 56.9%, including 3 patients with stringent complete response (sCR), 4 with CR, and 7 with very good partial response (VGPR). Neither age, number of prior therapies, TCR status, nor time from Dara refractoriness to IsaPd initiation significantly affected response rates. Median progression-free survival (PFS) was 5.8 months, with a 12-mon
